Figure 2 is a top plan view thereof. Within the frame A is a power motor I3, in this Figure 3 is a view similar topFigure 1 looking instance, of the internal combustion type, and toward the opposite side of themachine, the same its driving shaft Il, through the connecting belts 55 I5 and I6, respectively, transmits power to the traction mechanism II for the driving of its belts I2. The power shaft I4 of the motor carries the sprocket wheel I1 for the belt I5 and the traction mechanism II has its driven shaft I8 carrying the belt wheels I9 for the belt I6, it being understood that these pulleys are located at opposite sides of the frame. The belt I5 is also trained over a sprocket wheel 20 xed to a driven shaft 2| journaled in bearings 22 transversely of the frame A, the bearings being fixed in the latter in any suitable manner, while each belt I6A is trained over a belt wheel 23 loose on the driven shaft 2I and made secure thereto by a clutch 24, there being two of these clutches for the pair of belt wheels 23 and such clutches 24 are independently operated through a shift lever 25 capable of manual control for the clutching action. The pair of belts I6 and the belt wheels I9 and 23 therefor are provided in conformity with the character of the traction mechanism II, as this includes a traction belt I2 at each side of the frame A of the machine and the driving of these belts independently of each other can be had by providing the clutches 24.

At the forward or front end of the frame A is arranged a swinging derrick or crane B having the trussed rig 26 fitted in a saddle 21 which is pivoted at 28 to mountings 29 on the body frame A, so that said derrick B can be swung from an upstandlng operating position, as in Figure 1, to a superimposed transporting position on the body frame A, as in Figure 3 of the drawings.

Arranged within the frame A is a bull wheel 38, itsI axle 3I being journaled in slidable bearing boxes 32, these fitting guide pieces or brackets 33 suitably built into the frame and said boxes have connected thereto shift rods 34 for their adjustment, the rods being manually controlled. The axle 3| for the bull wheel 30 is formed with a crank end 35 to which is connected a pitman 36 which is connected, at 31, to a spudding or stroke beam 38 pivoted for its swinging movement, at 39, in the frame A, the connection 31 for the pitman 36 being eccentric to the axis of the bull wheel 30 so that the lift stroke of the beam 38 will be considerably greater than the fall or drop stroke thereof, or, in other words, the crank end 35 will be required to travel approximately two-thirds of the circular course thereof for the completion of the lift stroke of the beam 38, while the fall or drop stroke requires the remaining approximate one-third of the circle for the completion thereof for a purpose presently described.

The power shaft I4 of the. motor I3 carries the belt wheel 40, over which is trained a driven belt 4I, the same being trained over a belt wheel 42 upon an auxiliary drive shaft 43 vjournaled in bearings 44 tted in the frame A, this shaft being disposed transversely of said frame and carrying a belt pulley 45 having trained thereover the belt 46 which is also trained over the bull wheel 30 so that power from the motor I3 will be transmitted to the bull wheel.

In the frame A, at opposite sides with respect to the shaft 43, are arranged the upper and lower shafts 41 and 48, respectively, these shafts 48 being fixedly journaled in suitable bearings 49, built into the frame A, while each shaft 41 is supported in a swiveled bearing 50 and a slide bearing 5I, respectively, so that this shaft can be swung in a horizontal plane. 'Ihe shafts 41 have fixed thereto gears 5I adapted to be brought into and 43 andthis pinion is formed with a brake drum 53 and one member 54 of a clutch, the other member 55of the latter being splined or keyed upbn the shaft 43 and operated upon by a throw lever 56 operable from a control 51, so that the part 55 can be brought into engagement with or out of engagement from the ,part 54 Iof said clutch, and the control 51 being manually operated. Embracing the drum 53 is a brake band 58 which is tightened for braking purposes by alever 59, the same being arranged in the path of movement of the throw lever 56 when the part 55 is thrown out of engagement with the part 54 of said clutch, so that on the release of the clutch the brake will be applied. When the clutch is engaged the brake will be released so that power from the auxiliary shaft 43 will be transmitted to the shaft 41, provided the gears 5I thereon are meshing with the pinion 52 controlled by the said clutch and brake.

Fitted upon each shaft 41 is a transmission and reverse mechanism including a circular housing 60 having journaled therein a train of transmission gears 6I, 62, 63 and 64, respectively, the housing being open, at 65, for accommodating the gear 66 fixed to each of the shafts 48 so that the gears 63 and 64 can be brought alternately into mesh therewith. 'I'he gear 63 meshes with the gear 62 which meshes with the gear 6I, while the gear 64 meshes with the said gear 6I and this gear is fixed to the shaft 41. 'Ihe housing 6I) is rotated clockwise and counterclockwise byy said drum 68, while the utility drum 68 is adapted for the winding thereon and the unwinding therefrom of a utility cable 1I and this drum may also carry a supplemental or additional utility cable 12.

Loose upon the shafts 41 are the drums 13 and 14, respectively, each at one end being provided with a brake drum 15 and a part 16 of a clutch, the part 11 of said clutch being keyed or splined with the shafts 41, while trained about the drum is the brake band 18, this being controlled by the lever 19 in the path of the throw arm 88 for the part 11 of the clutch. On the throwing out of the clutch, the brake will be automatically and simultaneously applied.- The drum 13 is adapted for the winding thereon and the unof a clutch, the part 8| of the latter being splined or keyed to said shaft 2I and moved by a throw lever 92, while surrounding the drum 9| is the brake band 93, this being operated by a lever 94 in the path of the lever 82 so that when the clutch is opened or thrown out the brake will be automatically and simultaneously applied therewith.

The shaft 83 has xed thereto the bailing tool cable 95 which is adapted to be wound on and unwound therefrom, while the shaft 84 has loose thereon an crane cable drum 96, the same being formed at one end with the brake drum 91 and the part 98 of a clutch, the other part `99 of the latter being splined or keyed upon said shaft 84 and operated by the throw lever in the path of which is the brake-band lever |0| controlling the brake band |02 about the drum 91, the brake being released when the clutch is closed or its part 99 interfltted with the part 98 of said clutch. This drum 96 carries the crane cable 96'.

In the frame A, beneath the upper shaft 84, is the lower shaft |03, this being journaled in fixed bearings |04 built into said frame and this shaft has fixed thereto a double drum for the winding thereon and unwinding therefrom of the hook cables |06 and |01, respectively. The shaft |03 also has fixed thereto a gear |08 cooperating with a transmission including the circular housing |09 containing the train of gears H0, these in number and arrangement being alike to the gears 6|, 62, 63 and 64, respectively, hereinbefore referred to, one gear of the train being xed to the shaft 84 and the housing |09 is operated by a control manually operable, so that the shaft |03 can be readily reversed for rotation clockwise or counterclockwise, while power from the shaft 84 can be transferred to the shaft |03. It should be apparent that the transmissions hereinbefore referred to can be shifted to neutral so that power therethrough will be cut off to their cooperating parts. The housings 60 and |09 are freely rotatable upon their supporting shafts and the same are moved by hand for the control of the transmissions.

Upon the spudding or stroke beam 38 are mounted suitable guide pulleys H2 for the drilling tool cablelll, while suitably arranged in the frame A are conventional pulleys ||3 for the cables adapted to be wound on and unwound from the drums.

Located centrally of the derrick or crane B and disposed longitudinally of the saine is a guide tube or easement ||4 in which is slidably fitted a mast H5 which, at its upper end, supports a pulley ||6 arranged within a head lil' which is a part of the mast and is outside of the derrick or crane. Over this pulley I6 is trained the drilling tool cable l0. The inner or lower end of the mast H5 carries a cross guide ||8 fitted in guides ||9 in the derrickor crane at the lower portion thereof beneath the cross piece |20 Y for the tube or easement I|4, which cross piece is suitably secured in place within the derrick or crane. This cross guide ||8 has fitted therewith the stems |2| yof plungers |22, these operof the derrick or crane and such springs |23^ function as shock absorbers for the mast H5.

AThe derrick or crane B has supported thereon suitable guide pulleys |25 over which are trained the other cables of the rig.

Carried by the derrick or crane Bis a boom |26 which has its lower end connected with the saddle 21 through the medium of a universal joint or connector |21 and this boom carries pulleys |28 for certain of the cables of the rig, one pulley carrying the cable 96'- and the other the cable 82.

Mounted on the cross guide ||8 is a pointer |29 co-operating with a graduated scale plate |30, the latter being carried by the derrick or crane so that the pointer |29 will traverse the scale marks of said plate |30 and this will disclose the displacement of the mast ||5 in the operation of the drilling machine.

Certain of the cables of the rig are provided with hooks |3| at their free ends for hitching purposes in the drilling maneuver.

In the operation of the machine it will be apparent that the derrick or crane is swung from inactive position upon the frame A of the machine to the working position as shown in Figure 1 of the drawings vand the cables on the drums heretofore referred to can be let off of such drums as the occasion may require and said cables wound thereon under power from the motor I3, the controls for the drums'being selectively operated and the rotations of such drums reversed at the option of the operator of the machine.

The front steering wheels I0 are actuated by steering mechanism |32 so that the machine, in transit, can be guided in the desired course.

The stroke action upon the drilling tool cable l0 is clearly shown in Figure 7 of the drawings and this stroke has a greater arc of movement than the fall or drop stroke for the tool, the cable 'i0 being let out from its drum 68 in conformity with the depth of cut of the well and, as heretofore stated, the drums in their working are independently controlled. The speed of the bull wheel 30 is regulated by shifting the same forV the tightening or,slackening of the belt 46the bull wheel 30 being shifted by the slide bearings 32 regulated by the controls 34.

The machine is `advanced or moved in the de. sired course by the traction mechanism having the traction belts I2 and these are operated .independently or jointly through the clutches ing boxes built into said frame and having longitudinal sliding movement therein, a bull wheel having an axle journaled in said bearing box, a spudding beam swingingly mounted at one end on the frame, a crank operated by the bull wheel and carried by its axle, a pitman connected 'with the crank and to the spudding beam to have the lift stroke of the beam operate in an arc greater than the full stroke of said beam and a power source within the frame for driving said bull wheel.
